Genuine Toyota OEM Spark Plugs

The job of spark plugs is to ignite the mixture of fuel and air in a vehicle's engine. The process, called "spark ignition," starts when the key turns in the ignition lock cylinder. An ignition switch triggers, and the car battery, plus a few other ignition parts, like the starter motor, starter solenoid, and ignition coil, get working. Together, they "spark" a small electric charge, which the plugs' leads capture. Combustion occurs inside the engine, its pistons start pumping, its crankshaft begins turning, and automotive systems start running on their own power.

No spark plug lasts indefinitely, though. Sometimes, their leads can get rusty or widen too far, affecting their ability to conduct electricity. If the engine's misfiring or failing, for instance, it's probably because the spark plugs are bad. Broken ones, however, are a worse scenario: they can badly damage an engine's cylinders. If you're seeing any of these issues with your Toyota or Scion vehicle, inspect the spark plugs, and change any that the results call for replacing.

Those your OEM manufactures for your model will your best choice. They're tough enough to last up to about 100,000 miles. That means millions of ignitions. In fact, these kinds often get called "extended-life" because of that. Copper spark plugs, for instance, are ideal for everyday driving in normal conditions, while platinum or iridium spark plugs, for example, will better resist wear. Just don't let any of them exceed their recommended mileage limits.
